Abstract

The invention relates to a method used to increase inking printing dye ink color fastness. It includes the following steps: orderly adding dye color paste, polyhydric alcohol, adhesive, cross linking agent, surface activator in proportion into container; adding water to mix evenly; stirring, filtrating to form super fine dye ink; jet printing on the fabric; drying, baking to fix. The printing film formed by cross linking agent makes the super fine dye particle can tolerate dry wet friction, can increase its color fastness on the fabric without influencing on ink injecting performance.

Description

A kind of method that improves inking printing pigment ink color fastness
Technical field
The present invention relates to a kind of method that improves inking printing pigment ink color fastness, belong to technical field of textile printing.
Background technology
Along with the development of digitizing technique with popularize, the digital ink-jet fabric printing technique becomes the most potential ecological spinning technology of 21 century, and wherein digital inking printing is to solve one of key link of Digital ink jet printing technology with the research and development of pigment ink-jet inks.But because ink has added a large amount of polyalcohols in process for preparation.Easily cause the swelling of printed film under wet environment in spray printing hydrophily of polyalcohol after the fabric face, the fastness to wet rubbing that causes superfine pigment to adhere on fabric reduces.
In order to solve the low problem of ink-jet printed fabric fastness to wet rubbing, need carry out preliminary treatment to the fabric of spray printing or stamp product behind the spray printing is carried out post processing.So not only increase treatment process, improved production cost, and be easy to generate environmental pollution.Add crosslinking agent in printing ink, the ability that improves printed film tolerance wet environment becomes the shortcut that improves the ink print durability.Yet general film forming matter joins the problem that is prone in the ink-jet printing ink and is: (1) causes the gathering of superfine pigment particle in the ink, produces flocculation, precipitation; (2) quality of forming film is not high, after spray printing is to the fabric, can not form densification, continuous, smooth printed film at fabric face; Damaged easily when (3) printed film is rubbed under wet environment, cause pigment particles to come off.In inking printing pigment ink, add crosslinking agent and can overcome above-mentioned shortcoming.
Crosslinking agent is mainly used in finishing functions of textile fabrics in the textile printing and dyeing field at present, as: many aspects such as fabric anti-crease and Iron-free.
Chinese patent CN1039456A discloses with polybasic carboxylic acid COTTON FABRIC has been carried out technology and the employed catalyst that formaldehyde-free durable is pressed boiling hot arrangement, esterification and crosslinked takes place with cellulose in the textiles in the crosslinked character of this technology utilization polybasic carboxylic acid under the effect of catalyst, thereby obtains the durable press effect; Chinese patent CN1431359A discloses a kind of by using dihydroxy dihydroxymethyl cyclic ethylene urea, and BTCA or sol-gel technique are anchored at method on the textiles with cyclodextrin, develop the textiles with nest's effect; Chinese patent CN1552989A discloses a kind of formaldehyde-free crease-proofing finishing agent and manufacture method thereof, comprises acetic acid in this crease proofing agent, sodium acetate, chitosan and crosslinking agent citric acid, glyoxal; Chinese patent CN1566514A discloses a kind of crosslinking agent glyoxal and an amount of reformation agent ethylene glycol or diethylene glycol (DEG) of comprising, and mixture of catalysts is used for the wrinkle resistant processing agent of fabric; Chinese patent CN1621606A discloses the reactive organic silicon modified aqueous polyurethane wool anti-felting finish agent of a kind of anionic; Chinese patent CN1704523A discloses a kind of production process of the aqueous polyurethane with end-blocking or unsaturated bond structure and to the method for sorting of crease-proofing textiles containing, guarantor's type; Chinese patent CN1865579A discloses a kind of crease proofing agent at soybean fiber fabric, comprises: glyoxal, magnesium chloride, aqueous polyurethane, triethanolamine, softener and bleeding agent.
But crosslinking agent is used for pigment ink-jet inks textiles is carried out digital inking printing, improve the method for COLOR FASTNESS by the quality that improves crosslinked film forming and do not appear in the newspapers as yet.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of method that improves inking printing pigment ink color fastness, by in inking printing pigment ink, adding crosslinking agent, after the ink spray printing is to fabric, in the process of curing fixation, utilize the film properties that is cross-linked into of crosslinking agent, form continuously at fabric face, fine and close, smooth printed film, make the superfine pigment particle in the ink can tolerate dried wet friction, thereby reach the purpose that improves COLOR FASTNESS.
